What is the result of self-harm? The sky is falling. In fact, it means devastating consequences for your family life (you, your mother, son and other family members appear in your dreams).
So who are the family members who didn't appear in the dream? Those two competitors are among them, maybe two people with status and authority, but the dream didn't tell you directly.
It is also possible that the dream is to explain the conflict between partners in the company or business, but this is unlikely because the characters in the dream are all family members.
